Sway bar bushings will cause thumping on rough roads or when only one wheel hits a bump. If only really bad on one side, only that side will thump.

Track rod bushings on the W123 chassis will groan over large bumps at low speed (speed bumps) as well as thump. They will also make clunking noises when going from reverse to drive with the brakes on.

Sway bar bushings are easy on the W123 and later models. W115 and earlier can be a problem due to limited space and/or VERY tight clamping straps.

Next month I'm gonna do the sway bar bushings on both W124 cars (just did the evaporator on the TE and I'm out of cash).
